In May, he told the Houston Chronicle he was uncertain whether he wanted to play with Houston.

"Nobody's been here as long as I have. You just kind of look at things ... I've been thinking about things this offseason," Johnson said. "And I just kind of wonder sometimes, 'Is this still the place for me?' ''

He noted he's been to the playoffs just twice and been part of three winning seasons. "I don't think any player wants to experience that," he said in May.

Johnson skipped the Texans' offseason organized team activities and minicamp. He would have qualified for a $1 million bonus for participation in the OTAs.

ESPN reported that Johnson visited the Texans' complex Monday.

Bill O'Brien, previously coach at Penn State, is the new coach of the Texans. O'Brien, who also previously was offensive coordinator of the New England Patriots, will be running the Texans' offense.

Johnson could be fined $30,000 per day for missing training camp.

Under contract through 2016, he is due a base salary of $10 million this season.
